Hal, your right about Windows... very brain dead..in the tcp stack...
however, been googling the net and found this for linux tcp tuning.

Add the following to /etc/sysctl.conf

 # Tweaks for faster broadband...
 net.core.rmem_default = 524288
 net.core.rmem_max = 524288
 net.core.wmem_default = 524288
 net.core.wmem_max = 524288
 net.ipv4.tcp_wmem = 4096 87380 524288
 net.ipv4.tcp_rmem = 4096 87380 524288
 net.ipv4.tcp_mem = 524288 524288 524288
 net.ipv4.tcp_rfc1337 = 1
 net.ipv4.ip_no_pmtu_disc = 0
 net.ipv4.tcp_sack = 1
 net.ipv4.tcp_fack = 1
 net.ipv4.tcp_window_scaling = 1
 net.ipv4.tcp_timestamps = 1
 net.ipv4.tcp_ecn = 0
 net.ipv4.route.flush = 1
------------
Now, I thought I would as,k the the network specialist
out there, if these setting would make any real diff.

Thanks -
